if (x0,y0) is the center point of a circle, then

(x - x0)^2 + (y - y0)^2 = r^2

the equation is (x-4)^2 + (y-1)^2 = 4

Answer:


(x-4)^(2)+(y-1)^(2) =4

Explanation:

we know that

The equation of a circle in center radius form is equal to


(x-h)^(2)+(y-k)^(2) =r^(2)

where

(h,k) is the center of the circle

r is the radius of the circle

In this problem we have


(h,k)=(4,1)


r=2\ units

substitute


(x-4)^(2)+(y-1)^(2) =2^(2)


(x-4)^(2)+(y-1)^(2) =4
